  • Title: A delay in the appearance of myosin in dystrophic chicken embryos.
    Author: Allen ER, May JF.
    Journal: Anat Anz; 1986; 161(3):239-42. PubMed ID: 3717599.
    Abstract:
    Growth patterns during myogenesis were observed in vitro using normal and dystrophic New Hampshire Red chick embryos. The pectoral muscles from 6 d old embryos were removed, dissociated and grown in culture. Smaller muscle straps, both in size and number, as well as pseudostraps were seen in cultures from the myopathic embryos. There was a 1 1/2 d delay in the appearance of thick myosin-like myofilaments as well as large polyribosomes actively synthesizing myosin in the dystrophic muscle cells. Myosin may be a necessary constituent during myogenesis for the occurrence of normal fusion and thus myotubes.
